The PVSG Dataset comprises 400 videos characterized by their length (averaging 76.5 seconds), perspective diversity (combining first and third-person views across different scenarios), and dynamism (featuring significant camera and object motion), with rich annotation includes Video Panoptic Segmentation and Temporal Scene Graph on 150K frames, and video-level dense captions and QA pairs. Here we show some examples. All 400 visual examples are [here].

Abstract

Towards building comprehensive real-world visual perception systems, we propose and study a new problem called panoptic scene graph generation (PVSG). PVSG is related to the existing video scene graph generation (VidSGG) problem, which focuses on temporal interactions between humans and objects localized with bounding boxes in videos. However, the limitation of bounding boxes in detecting non-rigid objects and backgrounds often causes VidSGG systems to miss key details that are crucial for comprehensive video understanding. In contrast, PVSG requires nodes in scene graphs to be grounded by more precise, pixel-level segmentation masks, which facilitate holistic scene understanding. To advance research in this new area, we contribute a high-quality PVSG dataset, which consists of 400 videos (289 third-person + 111 egocentric videos) with totally 150K frames labeled with panoptic segmentation masks as well as fine, temporal scene graphs. We also provide a variety of baseline methods and share useful design practices for future work.
